What this means for you
- It charges only as a percentage of the assets it manages. Ask about the fee schedule and any account minimum, which Form ADV Part 1 does not record.
- Most of its individual clients are not high-net-worth, so it is likely to work with people who are still building assets.
- It sponsors or manages a wrap fee program; ask what the bundled fee covers.
- It reports disciplinary history on Form ADV. Read the disclosure details on its SEC record before you engage it.
Before you hire any adviser
Read the firm’s Form ADV Part 2 brochure on its SEC record: it sets out fees, minimums, conflicts of interest and who will manage your money. Ask whether the firm acts as a fiduciary for all of your accounts, how it is paid in total, and who holds your assets. Our guide to choosing a financial adviser lists the questions to ask.
